Thanks. This seems to be showing me how to compute in Postscript. I'm
happy enough to do computation in LaTeX because I don't know Postscript.
But either way, I need to do computation with numbers known to LaTeX,
not just constants (180, 2, etc.). Suppose I have the angle I want in a
TeX counter; how do I pass that number to \ncarc (or to Postscript)?
